Mid-infrared (IR) spectroscopic imaging using inherent vibrational contrast has been broadly used as a powerful analytical tool for sample identification and characterization. However, the low spatial resolution and large water absorption associated with the long IR wavelengths hinder its applications to study subcellular features in living systems. Recently developed mid-infrared photothermal (MIP) microscopy overcomes these limitations by probing the IR absorption-induced photothermal effect u...

Mid-infrared photothermal (MIP) microscopy overcomes the resolution and huge water background limits in conventional mid-infrared imaging by probing the mid-infrared absorption induced photothermal effect. However, to detect the subtle MIP signal, large probe power and lock-in detection are needed, which limit the imaging speed of current MIP systems. To overcome this limitation, we develop a single-pixel pump-probe camera that leverages the large well-depth capacity of photodiode to achieve hig...

Traditional electrochemical measurements based on either current or potential responses only present the average contribution of an entire electrode's surface. Here, we present an electrochemical photothermal reflectance microscope (EPRM) in which a potential-dependent nonlinear photothermal signal is exploited to map an electrochemical process with sub-micron spatial resolution. By using EPRM, we are able to monitor the photothermal signal of a Pt electrode during the electrochemical reaction a...
